ABSTRACT:
A pneumatic cushion or bolster adapted to function as a bumper for boats, as protective packaging and as pneumatic elements included in wearing apparel. The bolster is composed of a non-stretchable fabric casing shaped to define, when fully expanded, a bolster in a configuration appropriate to its intended use, the casing having a small, closable port therein. Inserted through the port in its unexpanded state is a rubber balloon whose stem initially projects out from the port to permit mouth inflation of the balloon to an extent causing it to engage and conform to the inner surface of the casing. The stem is then tied and pushed within the casing, after which the port is closed, thereby fully encasing the balloon to provide a bolster having pneumatic properties.
